Grant access to a group through your acls and then make these
administrative users members of it. Here is a sample acl:

access to dn=".*,ou=People,dc=mydomain,dc=ca" attr=userPassword
by self write
by dn="uid=root,ou=People,dc=mydomain,dc=ca" write

by dn="gid=admin,ou=Group,dc=mydomain,dc=ca" write

by * auth

Also in your scripts, make sure that you manage concurrent accesses. If
all the scripts are on the same machine, you can use a semaphore for
this. If they are on different machines it get's more complicated.
